The topic: The revolution of Europe's energy systems will require huge investments to limit the detrimental social and environmental impact of our ever increasing energy consumption. In order to make sound decisions with regard to the allocation of financial resources the real costs of the different energy technologies need to be considered in a life cycle perspective. This means that the external costs of competing energy technology options need to be assessed in detail. The conference will discuss the following issues: What are the real costs of the different energy sources and technologies? What is the development potential of new power plant technologies within a European and global energy supply system? What are the main socio-economic driving forces affecting their future development? What can be done to improve acceptability and therefore foster a more extensive use of externality valuation? Is it possible to differentiate energy technologies based on their sustainability performance? How to determine fair and efficient charges (end use prices) of energy?The Conference will last 1,5 days:
